' -Be it known that 1, DAVID N. GIBSON regheny and State of Penns lvania, have invented certain new and use ul Improvements in Water-Heaters, of which the followingis a specification.

My invention relates to certain new and useful improvements in water heaters of the gaseous fuel type, burning either natural or artificial gas.

Generically, my invention embodies a suitably supported burner which is adapted to cooperate with a heating drum and coil to heat the water, which operating through a circulating system, performs its useful functions. Com ined with the burner is a housing which also forms a sup ort for a water reservoir or tank in which t e heated water I tail and then be specifically pointed out in the appended clalms, reference being had to the accompanying drawings, in which Figure 1, is a perspective view showing my invention. Fig. 2, 1s a central, vertical, lonitudinal section thereof. Fig. 3, is an enarged central section of a part of my invention. Fig. 4, is a horizontal section on the line 4-4 of Fi 3. Fig. 5, is a horizontal section on the ine.5'5 of Fig. 3. Fig. 6, is an enlarged detail section of the water valve showin the position of the 1 arts when the se iment in the coil is eing blown out. Fig. 7, is a similar view showing the osition of the arts when the sediment in t e drum and t e tank is. being blown out.

. Referring now to the accompanying drawin s, in which like letters and numerals of re erence indicate like parts in all of the figures, 1 represents a base which supports a standard consisting of a ipe 2 that is threaded, or otherwise secure to the bottom of a.

heatin drum 3 and is in communication Specification of Le'tterl'ratent.

Application filed December 11, 1907. Serial No. 406,084.

a The cold water inlet pipe 9 I Patented much as, 1900.

conical shape in side elevation with its a ex endjoined to the pipe 2, and is corrugate to offer a large heating surface.

The up ersurfaceof the drum 3 is centrally a erture to receive the enlarged end 4 o a circulatory pipe 4, which projects up into the boiler 10 hereinafter again referred to. The pipe end 4: has an internal longitudinal partition 4 dividing the same into two passage-ways, 4-4 and this pipe has its section with the assage 4 pro ect' downwardly into the rum 3-to its apex e 35 while the section having thepassage 4 terminates at the top of the drum. The pipe 4 has an aperture 4 in its enlarged portion 4 at the upward limit of the passage 4 to serve as a water inlet to such passage from the boiler or tank. The ipe 4 continues up to near the top of the bo er or tank wherein it discharges.

Surrounding the heatin drum 3 is a heating coil 5, one end of which joins with the pipe section 4 and communicates with the passage 4 thereof, while the other end of the coil connects with a two-way valve 6 that is in turn connected with the ipe 2 beneath the drum by a by-pass or ateral 2, for a purpose hereinafter explained.

A ring-like burner 7, preferably of the Bunsen ty e, surrounds the ipe 2 below the drum 3 to eat the drum an coil, the burner having the usual as inlet bell or mouth 7", as indicated. A t ermostatic gas valve 11, cooperates with the bell 7 to supply the burner with fuel.

8 designates a housing for the burner, the

drum, and the coil, the housing being secured on the pipe 2 by a collar and nut 8 for adjustment along the pipe. The housing incloses the burner, the drum and coils, but has its upper end 0 ened and is adapted to form a support for t e boiler or reservoir 10 leaving the bottom of the reservoir exposed tothe heat of the burner, and thus acting as an auxiliary heatin surface. A flue opening 8 and an air i et 8 may be provided in the housing.

asses to the bottom of the tank or receptac e 10 through its top, while the hot water off-take pipe 9 connects with the top of the tank, as shown.

The water'valve 6 is a two-way one, having an outlet port 6 in its casing and passages 6 66 in its rotary member, a lfiandle 6 being provided to turn such memer.

When the valve is in the position shown in Fi 6, the full Water pressure acts to blow out t e sediment in the coil 5, while when the valve is in the position shown in Fig. 7, the pig e 2, drum 3 and tank will be blown out. he normal position of the valve is that shown in Fig. 2. a

The pipe section .13 enters the bell 7 of the burner to discharge the gas therein. Gas is admitted from the source of supply to a connection 11 as indicated.

The manner in which my invention operates will be best explained 'as follows: Assume the cold water mlet Ipipe 9 and the hot water outlet pipe 9 to e connected to a a circulating system, the operator turns on pipe connected wit the valve 14 to permit gas-to flow through the thermostat to the burner at which point it is ignited. The heat of the burner acting u on the coil, the drum and the bottom of t e tank, serves to warm the Water therein, causes the cold water to flow into the passage 4" of the ipe section 4, see arrows in Fig. 3, and is discharged into the bottom of the heating drum from'which' it flows u ward of the pipe 4 and isdischarged at t e top of the tank, a portion of said cold water that is discharged at the bottom of thedrum flows through the pipe 2 and by-pass 2 to the water valve 6 and from thence throu h the heating coil and is discharged into t e pipe 4 at its section 4, above the heating rum. The water in the pipe 4 will there-. fore be hot water and will ascend to the top of said pipe where it is discharged in the tank at the top thereof, as stated. The hot water may be then drawn off from the'tankand cold water admitted through the cold water i e .tom 0 i516 tank for a ur ose well understood. The heat of t e alone upon the heating drum and coil but as well upon the bottom of the reservoir or tank'thus causing the water at that lace to become partially heated and ascen to the topNof the tank. I

hile I have made a brief reference to a thermostatic device in .the drawings and s cifications of this application, I make'no c aim thereto in this application as the same per se, forms the subject matter of another ap lication.
